keymap: Add option `unlockOnPress` for LockMods() It enables e.g. to deactivate CapsLock on press rather than on release, as in other platforms such as Windows. The specification of `LockMods()` is changed to: - On key *press*: - If `unlockOnPress` is true and some of the target modifiers were *locked* before the key press, then unlock them if `noUnlock` false. - Otherwise: - add target modifiers to *depressed* modifiers; - if `noLock` is false, add target modifiers to the *locked* modifiers. - On key *release*: - If `unlockOnPress` is true and triggered unlocking on key press, do nothing. - Otherwise: - remove modifiers from the *depressed* modifiers, if no other key that affect the same modifiers is down; - if `noUnlock` is false and if any target modifiers was locked before the key press, *unlock* them. It fixes a [12-year old issue] inherited from the X11 ecosystem, by extending the [XKB protocol key actions]. As it is incompatible with X11, this feature is available only using the keymap text format v2.
